Frog populations around the world are declining. The situation is due primarily to the destruction of terrestrial and aquatic habitats, environmental degradation, pollution, and climate change. These factors also have great impact on Canada’s frog population

The northern leopard frog was once the most widespread frog in North America. Beginning in the 1960s, however, its numbers began to decline. No one knows exactly why.
Today, Canadians are trying to restore the leopard frog.
As part of this effort, Parks Canada and partners are working to re-establish them in Waterton Lakes National Park of Canada.
